Former welterweight champion Andre Berto has tested positive for a banned substance, and the promoter of his rematch with Victor Ortiz next month says the fight is off.
Golden Boy Promotions CEO Richard Schaefer says Berto tested positive last weekend, and a secondary test also came back positive Friday.
Berto and Ortiz are scheduled to fight June 23 at Staples Center in Los Angeles. Ortiz handed Berto his first career defeat in a thriller in April 2011.
Schaefer says the card is still on, and Golden Boy will announce a replacement opponent for Ortiz in the next few days.
The fighters agreed to testing for the rematch through the Voluntary Anti-Doping Association, a Las Vegas-based organization that tests blood and urine for steroid use and other banned substances.
